 *  Less than one percent (1%).

(1)  Assumes conversion of all of the holder's LYONs at a conversion rate
     of 4.4294 common shares per $1,000 principal amount at maturity of the
     LYONs. This conversion rate is subject to adjustment, however, as
     described under "Description of the LYONs--Conversion Rights." As a
     result, the number of common shares issuable upon conversion of the
     LYONs may increase or decrease in the future. Does not include common
     shares that may be issued by us upon purchase of LYONs by us at the
     option of the holder.

(2)  Calculated based on Rule 13d-3(d)(i) of the Exchange Act, using
     40,351,310 common shares outstanding as of November 26, 2001. In
     calculating this amount for each holder, we treated as outstanding the
     number of common shares issuable upon conversion of all of that
     holder's LYONs, but we did not assume conversion of any other holder's
     LYONs. Does not include common shares that may be issued by us upon
     purchase of LYONs by us at the option of the holder.

(3)  Information about other selling securityholders will be set forth in
     prospectus supplements, if required.

(4)  Assumes that any other holders of LYONs, or any future pledgees,
     donees, assignees, transferees or successors of or from any such other
     holders of LYONs, do not beneficially own any common shares other than
     the common shares issuable upon conversion of the LYONs at the initial
     conversion rate.
